There are upon record a certain number of cases in which two or more urinary bladders are said to have existed. Of these some appear to me to have been cases in which the plurality was maintained merely because the organ was divided into compartments, either as a consequence of arrested development or of the formation of pouches, by the protrusion, or hernia of the mucous membrane of the organ.

Dr. Chamneys observes, that during fœtal life the mucous layer of the prepuce is always blended with the glans, and that with approaching birth the adhesion melts away. Adherence of the prepuce after birth is thus the result of arrested development. To draw back the foreskin is extremely advisable, lest the lingering adhesions undergo further thickening.
